Subject: [PATCH v2 0/6] hwrng: imx-rngc - use polling instead of interrupt
Date: Thu, 24 Aug 2023 21:20:53 +0200 [thread overview]
Message-ID: <20230824192059.1569591-1-martin@kaiser.cx> (raw)
Use polling and wait actively for the self test and the initial seeding
of the rngc to complete. This is much simpler than using an interrupt
and a completion.
v2:
- set reasonable timeouts
- separate commit for the removal of interrupt handling
- readl_poll_timeout does not wait in the foreground
Martin Kaiser (6):
hwrng: imx-rngc - reasonable timeout for selftest
hwrng: imx-rngc - reasonable timeout for initial seed
hwrng: imx-rngc - use polling to detect end of self test
hwrng: imx-rngc - read status register for error checks
hwrng: imx-rngc - use polling for initial seed
hwrng: imx-rngc - remove interrupt handler
